I Specification of Letters Patent. Application filed may as, 1912. Serial No. 699,750.

Patented Apr. '7, 191a.

To all 40/: am it may concern lie it known that I, FERNANDO CAsA- nmncxs', a subject of the King of Spa n, residing at Sabadell, Barcelona, Spam, have invented certain new and useful Improvements in Spinning-Frames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and tise the same.

My invention relates to spinning frames and consists in the constructions, arrange-- ments and combinations of parts hereinafter described and claimed.

It is an object of my invention to provide a spinning frame for drawing fibers of different lengths and conducting the same into close proximity to the drawing rollers whereby the drawing is effectedover a relatively small length of the roving.

Another object of my invention is to provide a spinning frame adapted to short length fibers and to maintain the latter under pressure throughout their length and to provide for adjusting the pressure means to accommodate fibers of varying length.

In describing my invention in detail reference will be had to the accompanying drawing, wherein like symbols refer to'like or corresponding parts throughout the several views, and in which Figure 1 is a vertical sectional view of my improved spinning frame. Fig. 2 is a similar viewv disclosing a slight modification. Fig. 3 is a detail. Fig. 4 is a detail of a'slight modification, and Fig. 5 is an end view of a different form of spinning frame. Referring more particularly to Figs. 1 to 4 of the drawings, 1 and 2 designate a pair of endless belts running over, respectively, pairs of rollers 4 and 5 suitablv mounted on the, framework. The rollers 4. are enlarged and constitute the feeding rollers for receiving the roving, while the rollers 5 are relatively small so as to enable the same to be located in close proximity to the drawing rollers 3, which, as usual, run at relatively higher speeds and pass the attenuated fibers to the bobbin as shown and as will be understood. .A tension roller 6 adjustably secured to the frame, as shown, provides for taking up slack in the belt 2, and a weight-controlled tension roller 7 bears against both belts at a' point intermediate belts l and 2 to the substantially uniform venting any creeping of the rollers 4 and 5, and in addition to compensating for the slack imparts the initial pressure to the roving 11 which is fed between the rollers 4 and conducted by the rollers 5. Between the tension roller 7 and the pair of rollers 5 is located a convex plate 9 sosupported from the frame as toelevate the belts vertically/ from the tension roller 7 and provide for pressure exerted over approximately the entire length of the fibers treated. This plate 9 extends in close proximity to the rollers 5 and supports the fibers as they are being drawn, thereby prethe same and obviating entanglement.

In place of the plate 9 I may/employ a segmental support 12, as shown in Fig. 2, carrying a plurality of rods or rollers 13 preferably spaced apart in parallel relation. While this construction does not yield as perfect and continuous a pressure as that disclosed in Fig. 1, yet, especially in the case where rollers are used, the wear on the belt 2 is reduced and the resistance lessened so as to be an economy as regards the motive power.

Figs. 3 and 1 show details of the bearings of the rollers 5 and means associated therewith to supply the proper tension. In Fig. 3 the lower roller is journaled in a fixed bearing, while the upper roller is mounted in a rocking bearing 25 oscillating about a pivot 26 ing arm through which a set screw 28 loosely passes and is threaded into the frame to regulate the required tension. A coil spring 27 encircles the set screw 28 and is adapted to maintain the arm normally in contact with the screw head.

Fig. 4 discloses a bearing block 31 accommodating both journals of the roller 5 and a fiat spring 29 secured at one end to the bearing block and having its free end engaging against the upper roller journal. A set screw 30 is arranged intermediate the ends of the spring 29 and regulates the tension as will be understood.

In Fig. 5 I have illustrated a form of my invention in which I dispense with one of the endless belts 1, together with its necessary parts, and supply in place thereof a pressure plate 15. The plate 15 is removably carried by a frame 18 in which is journaled a pair of rollers 19 and 20, over and having a rearwardly-extendwhich is trained the endless belt 2. The rollers 19 and 20 constitute the feeding rollers and receive the roving 11.

In order to accommodate fibers of different lengths the frame 18 carrying the feed rollers 1s adjustable so as to vary the distance between the latter and the drawing rollers, and for this purpose the frame 18 is mounted in a slotted bracket 16 and provided with a set nut for maintaining the frame in any adjusted position. After the frame 18 has been adjusted, as required, a plate 15 of a length to correspond approximately to the average length of the fibers treated is put in lplace and the operation proceeded with. T e plate 15 extends down to a position over the roller 5 and has its end preferably beveled so as not to come in contact with the upper drawing roller 3 while being permitted to occupy a position in close proximity thereto.

I have shown and described preferred and satisfactory constructions, but desire it to be understood that slight ehan es may be resorted to without departing rom the spirit and scope of my invention, provided such changes fall within the scope of the appended claims.

I claim:

1. In a spinning frame, a pair of drawing rollers, a pair of feeding rollers, a movable framecarrying said feeding rollers and adapted to be adjusted to vary the distance between said drawing and feeding rollers, an endless belt trained over said feeding rollers'for conducting the fibers in 'roximity to the drawing rollers, and a la efiremovably carried by said frame an of a length to eorres ondapproximately to the adjusted distance etween said drawing and feeding rollers, said plate being adapted to exert a substantially uniform pressure upon the fibers. L

2. In a spinning frame a pair of draw ing rollers, an endless be t for c'onductin the fibers to said drawin rollers a air 0% movable rollers over w ich said elt is trained and adapted to receive the fibers, and a plate ofa length corresponding to the average length of the fibers being treated extending between said movable rollers and the drawing rollers and exerting a substantially uniform pressure upon the fibers.

3. In a spinning frame a pair of drawin rollers, a pair of feedmg rollers adjustab e with respect to said drawing rollers to accommodate fibers of different length an endless belt trained over said feeding rollers for conducting the fibers in proximity to the drawing rollers, and a plate of a length to eorres 0nd to the average len h of the fibers exten ing between said mova 1e rollers and the drawing rollers and exerting a substantially uniform pressure upon the fibers.

In testimony whereof, I afiix my signature, in resence of two witnesses.
